The failure on the side of squad then isn't so much in not paying them more (although that would certainly be one way to solve it), it's in not realizing that there can't be a middle ground.
What I don't get at all, no matter how you spin the story, is how anybody could be forced to overtime etc on pocket change. Sure, that stuff happens millions of times each day, but it would typically involve people at the brink of starvation in an isolated mining town or so. Remote tech workers with enough leisure time to fall deep into the rabbit hole of gaming don't quite fit that pattern.
It's called capitalism...
We would not be talking about this if it were a number of unmistakable volunteers quitting after running out of dedication. Add 200$/month and you get a situation where both sides are prone to confuse a bit of thank-you-cash with an actual job.
This is your competition.
